1LLINois y Lette/rs .Patent N 92,214, dated July 6,1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern:

Be it known that we, SAMUEL S. SHERMAN and Juneau/u1 G. SHERMAN, of McHenry, inthe county ot' McHenry, :nid Stute ot' Illinois, lnwe made zt new and useful Improvement in Post-Angers; und we do around the bundle in the shape of :t scroll.

The nztture ofour invention consists in making each lcutting-bit ot' the post-uuger in two or more parts,

es hereinafter described.,

To enuble those skilled in the nrt to manufacture und use our invention, we will proceed to describe the saine with purtieulnrity.

The saine letters ot' reference refer to the corresponding pui-ts in the diiierent figures.

A represents nu ordinary posl-uuger handle, with the point und screw-threzul, for screwing the auger thereto, und B is :L cross-piece, to which the angerbits C ure fastened by thebolts or rivets D, und it is secured to the nuger-hundleby being screwed thereon.

The cutting-edge ofthe enger-bits C is mede in two or more parts, in the form of tint tines, as is clearly shown in figs. 1 :md 2 et E, and they may be extended Aclear round, in two or more parts, each part being riv eted to the cross-piece'or they may be brought together nt the lineF, enehbit forming a single piece from that line beek.

The object of making the cutting-edge of the bitin separate narrower pieces, is to make :in enger that will eut the soil much easier than a. continuous cuttingedge, sneh asis now used, and operatein gravel, which gives it :t greet advantage over the old form of posteugers.

We do not wish to confine ourselves to a. two-bitted auger, such as shown in figs. l and 2, for the pertieuiur form of the eutting-edge ofthe auger-bit admits of al thick-eut being made, so that e single bit, extending quite round the handle, es shown in fig. 3, works successfully.

Having thus fully described the construction and operution of our improved post-auger, Y

What we claim, und desire to secure by Letters Patent, is-

A post-unger, with each bit or vcutting-edge made in two or more parts, substantially as and for the purposes specified. I A SAMUEL S. SHERMAN.
